Description

Technical Field

[0001] This invention relates to the field of pavement structure technology, specifically to a cast-in-place concrete pavement structure and its method. Background Technology

[0002] Road surface refers to one or more layers of road structure paved with road construction materials on top of the roadbed, allowing vehicles to drive directly on its surface. It has the functions of bearing the weight of vehicles, resisting wheel wear, and maintaining the smoothness of the road surface. Therefore, road surface is required to have sufficient strength, high stability, a certain degree of smoothness, and appropriate skid resistance.

[0003] Traditional cast-in-place concrete pavement structures typically involve gradually paving cement concrete to form the road surface. In urban roads, to prevent water accumulation in low-lying areas, drainage structures are often installed at the bottom of the concrete pavement to divert water and prevent waterlogging from affecting safety. However, traditional cast-in-place concrete pavement structures can only divert water; water still flows on the concrete surface, affecting road safety. Furthermore, during subsequent maintenance, the drainage pipes are prone to blockage due to long road sections, leading to poor drainage. Consequently, waterlogging still occurs when a malfunction occurs, and it is difficult to locate the blockage after water accumulation, making it impossible to quickly resolve the situation. Even after locating the blockage, it is difficult to clean the pipes, increasing the difficulty for workers and failing to meet usage requirements. To address the shortcomings of existing technologies, this invention provides a cast-in-place concrete pavement structure and method to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a cast-in-place concrete pavement structure and method. It utilizes a permeable pavement structure formed by a large-diameter permeable crushed stone layer, a small-diameter permeable crushed stone layer, a permeable leveling layer, and a decorative permeable surface layer. Water infiltrates directly without forming runoff, preventing road surface flooding. Multiple sets of drainage pipes and water channel pits enhance the pavement structure's permeability and drainage capacity. Inside the water channel pits, a steel structure base, a split-type filter box, and a primary large-aperture filter screen are installed. The primary large-aperture filter screen traps impurities at various drainage sections, preventing drainage pipe blockage. The split-type filter box, located inside the steel structure base, is easily disassembled, ensuring convenient cleaning and maintenance of both the filter box and the primary large-aperture filter screen. Combined with a water level monitoring mechanism, it can quickly locate blocked or flooded sections within the enhanced drainage channels formed by the drainage pipes and water channel pits, enabling rapid location of the blockage and preventing road surface flooding, thus ensuring road safety.

[0020] A method for constructing a cast-in-place concrete pavement structure, the construction method comprising the following steps:

[0021] S1: Use machinery to excavate drainage pipes and waterway foundation pits;

[0022] S2: Use a road roller to flatten the hard soil layer;

[0023] S3: Laying drainage pipes and connecting steel structure base;

[0024] S4: Lay a layer of large-diameter permeable crushed stone and compact it with a road roller;

[0031] S11: The main body of the maintenance cover is snapped onto the top of the steel structure base.

[0032] This invention discloses a cast-in-place concrete pavement structure and method, which has the following beneficial effects:

[0033] 1. This cast-in-place concrete pavement structure utilizes a permeable pavement structure formed by a layer of large-diameter permeable crushed stone, a layer of small-diameter permeable crushed stone, a permeable leveling layer, and a decorative permeable surface layer. Water infiltrates directly without forming runoff, preventing water accumulation on the road surface. Multiple sets of drainage pipes and water channel pits enhance the pavement structure's permeability and drainage capacity. Inside the water channel pits, a steel structure base, a split-type filter box, and a primary large-aperture filter screen are installed. The primary large-aperture filter screen traps impurities at each drainage section, preventing blockages. The split-type filter box, located inside the steel structure base, is easily disassembled, ensuring convenient cleaning and maintenance of both the filter box and the primary large-aperture filter screen. Combined with a water level monitoring system, it can quickly locate blocked or waterlogged sections within the reinforced drainage channels formed by the drainage pipes and water channel pits, enabling rapid location of the blockage and preventing water accumulation on the road surface, thus ensuring road safety.

[0034] 2. The water level monitoring mechanism installed in this cast-in-place concrete pavement structure has a simple overall structure and stable operation. When drainage is smooth, the water level inside the split-type filter box is normal, and the buoyancy block is lifted by the buoyancy of the water flow without contacting the pressure sensor. When drainage is obstructed, the water level rises and causes the buoyancy block to rise and contact the pressure sensor, triggering the communicator to work and send a warning message. The pressure sensor simultaneously compresses the third spring. The greater the compression of the third spring, the greater the detection force of the pressure sensor. Therefore, the message sent by the communicator can determine the blockage situation at the corresponding waterway pit.

[0035] 3. The cast-in-place concrete pavement structure features a convenient secondary filter body that provides secondary filtration for each waterway pit, preventing impurities from entering the drainage pipe. When the split-type filter box is inserted into the steel structure base, the secondary filter body is automatically inserted between the secondary filter body and the split-type filter box, ensuring stable insertion of the secondary filter body. This facilitates installation and subsequent disassembly, cleaning, and maintenance. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] This application provides a cast-in-place concrete pavement structure and method, solving the problems of traditional cast-in-place concrete pavement structures which can only guide water flow, leaving water flowing on the concrete pavement and affecting road safety. Furthermore, during subsequent maintenance, long road sections are prone to pipe blockage by impurities, leading to poor drainage. Therefore, water accumulation still occurs during malfunctions, and it is difficult to locate the blockage, making it impossible to quickly resolve the situation. Even after locating the blockage, cleaning the pipes is difficult, increasing the workload for workers and failing to meet usage requirements.

[0052] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0053] This invention discloses a cast-in-place concrete pavement structure, according to the attached... Figure 1-12 As shown, it includes a large-diameter permeable gravel layer 2 set on a hard soil layer 1, a small-diameter permeable gravel layer 3 set on the large-diameter permeable gravel layer 2, a permeable leveling layer 4 set on the small-diameter permeable gravel layer 3, and a decorative permeable surface layer 5 set on the permeable leveling layer 4.

[0054] Multiple sets of drainage pipes 6 are pre-embedded inside the hard soil layer 1, and multiple sets of water channel pits 7 are opened inside the hard soil layer 1. The water channel pits 7 are located between two adjacent sets of drainage pipes 6.

[0055] A steel structure base 8 is pre-embedded inside the waterway foundation pit 7. A split-type filter box 9 is movably connected inside the steel structure base 8. A primary large-diameter filter screen 10 is movably connected inside the split-type filter box 9.

[0056] The split-type filter box 9 is equipped with a water level monitoring mechanism, which includes a detection rod 12 fixedly connected inside the split-type filter box 9.

[0057] The main body of the maintenance cover 13 is movably connected to the steel structure base 8.

[0058] Specifically, the waterway pit 7 has a filter channel hole 701 inside, and a secondary filter screen holder 801 is provided on the steel structure base 8. The secondary filter screen holder 801 is movably engaged inside the filter channel hole 701, and a secondary filter screen body 802 is movably engaged inside the secondary filter screen holder 801. The secondary filter screen body 802 is easy to engage, providing secondary filtration for each location in the waterway pit 7, preventing impurities from entering the drain pipe 6. When the split-type filter box 9 is engaged inside the steel structure base 8, the secondary filter screen body 802 is automatically engaged between the secondary filter screen holder 801 and the split-type filter box 9, maintaining the engagement of the secondary filter screen body 802 stably, making installation convenient, and facilitating subsequent disassembly, cleaning, and maintenance.

[0059] Furthermore, the interior of the split-type filter box 9 is equipped with a locking rail 901, in which the primary large-pore filter screen 10 is movably locked. The locking rail 901 is equipped with a locking component for locking the primary large-pore filter screen 10. The locking component includes a locking seat 11 fixedly connected to the locking rail 901. A second sliding post 1101 is slidably connected inside the locking seat 11. A second locking rod 1102 is provided on the second sliding post 1101. A second locking hole 1001 is opened on the primary large-pore filter screen 10. The second locking rod 1102 is movably locked in the second locking hole 1001. The primary large-pore filter screen 10 is locked in position inside the locking rail 901 by the locking component, so that the primary large-pore filter screen 10 is installed and fixed stably inside the split-type filter box 9. It is also convenient for subsequent disassembly and maintenance, thereby ensuring good stability of the primary large-pore filter screen 10, easy replacement and maintenance after damage, and good interception effect of impurities.

[0060] Furthermore, the detection rod 12 is fixedly connected to the bottom of the locking seat 11. A bearing slider 1201 and a buoyancy block 1205 are sleeved on the detection rod 12. A third spring 1202 is fixedly connected between the bearing slider 1201 and the locking seat 11. A communicator 1203 is fixedly connected inside the bearing slider 1201. A pressure sensor 1204 is provided at the bottom of the communicator 1203. The overall structure of the water level monitoring mechanism is simple and the operation is stable. When the drainage is smooth, the water level inside the split-type filter box 9 is normal, and the buoyancy block 12... 05 is lifted by the buoyancy of the water flow and does not contact the pressure sensor 1204. When drainage is not smooth, the water level rises and causes the buoyancy block 1205 to rise and contact the pressure sensor 1204, triggering the communicator 1203 to work and send a warning message. The pressure sensor 1204 simultaneously squeezes the third spring 1202. The greater the compression of the third spring 1202, the greater the detection force of the pressure sensor 1204. Therefore, the message sent by the communicator 1203 can determine the blockage situation at the corresponding waterway pit 7.

[0061] Specifically, a second spring 1103 is fixedly connected inside the second sliding post 1101 and the locking seat 11. A second unlocking handle 1104 is fixedly connected to the second sliding post 1101. The second spring 1103 applies elastic force to the second sliding post 1101 and the second locking rod 1102, so that the second locking rod 1102 remains stable and not easy to loosen when inserted into the second locking hole 1001, thus making the large-diameter filter screen 10 lock effectively.

[0062] Specifically, the steel structure base 8 is provided with an inspection cover slot 803, and the inspection cover body 13 is movably engaged in the inspection cover slot 803. The inspection cover slot 803 facilitates the engagement, installation and positioning of the inspection cover body 13.

[0063] Furthermore, the inspection cover body 13 is provided with a first spring 1303 inside. The two ends of the first spring 1303 are fixedly connected to a first sliding post 1301. The first sliding post 1301 is slidably connected inside the inspection cover body 13. A first locking rod 1302 is fixedly connected to the first sliding post 1301. A first locking hole 8031 ​​is opened inside the inspection cover slot 803. The first locking rod 1302 is movably inserted into the first locking hole 8031. A first unlocking handle 1304 is fixedly connected to the first sliding post 1301. The internal components of the inspection cover body 13 are simple, ensuring a stable connection between the inspection cover body 13 and the steel structure base 8, and facilitating easy assembly and disassembly.

[0064] Furthermore, when the split-type filter box 9 is snapped into the inside of the steel structure base 8, the upper edge of the split-type filter box 9 is flush with the bottom wall of the inspection cover slot 803. When the inspection cover body 13 is snapped into the inside of the inspection cover slot 803, the split-type filter box 9 is limited.

[0065] Specifically, multiple sets of channel holes 601 are provided on the drain pipe 6 to facilitate drainage.

[0066] A method for constructing a cast-in-place concrete pavement structure, the construction method comprising the following steps:

[0067] S1: Use machinery to excavate the drainage pipe 6 and the waterway foundation pit 7;

[0068] S2: Use a road roller to flatten the hard soil layer 1;

[0069] S3: Laying drainage pipes 6 and connecting steel structure base 8;

[0070] S4: Lay a layer of large-diameter permeable crushed stone 2 and compact it with a road roller;

[0071] S5: Lay a layer of small-diameter permeable crushed stone 3 and compact it with a road roller;

[0072] S6: Lay a permeable leveling layer 4 and compact it with a road roller;

[0073] S7: Lay the decorative permeable surface layer 5 and compact it with a road roller;

[0074] S8: A split-type filter box 9 is snapped into the inside of the steel structure base 8;

[0075] S9: A large-pore filter screen 10 is snapped into the inside of the split-type filter box 9;

[0076] S10: Check the operational status of the water level monitoring device;

[0077] S11: The main body of the maintenance cover 13 is snapped onto the top of the steel structure base 8.

[0078] The cast-in-place concrete pavement structure uses a permeable pavement structure formed by a large-diameter permeable crushed stone layer 2, a small-diameter permeable crushed stone layer 3, a permeable leveling layer 4, and a decorative permeable surface layer 5. Multiple sets of drainage pipes 6 and water channel pits 7 are installed to enhance pavement seepage and drainage.

[0079] When the amount of water received by the road surface is small, the water directly infiltrates into the hard soil layer 1 and the underground layer through the cast-in-place concrete pavement structure.

[0080] When the road surface receives a large amount of water, the water that cannot infiltrate in time enters the drainage pipe 6 and multiple sets of waterway foundation pits 7 for discharge.

[0081] Inside the waterway pit 7, there are steel structure bases 8, split-type filter boxes 9, and primary large-pore filter screens 10. The primary large-pore filter screens 10 are used to intercept impurities and prevent them from clogging the pipes. At the same time, the split-type filter boxes 9 are easy to install and disassemble inside the steel structure bases 8, and the primary large-pore filter screens 10 are easy to install and disassemble inside the split-type filter boxes 9, thus ensuring that the impurities are easy to clean later.

[0082] The water level monitoring mechanism can detect abnormal signals in the split filter box 9 in a timely manner. If an abnormal signal is detected, it indicates that there is a blockage inside the split filter box 9, which needs to be cleaned and maintained. The water level monitoring mechanism can quickly locate the location of the blockage in the water channel pit 7, thereby avoiding water accumulation on the surface of the cast-in-place concrete pavement structure caused by the obstruction of the water channel of the entire drainage pipe 6 and the water channel pit 7.

[0083] Before installing the steel structure base 8 and the split filter box 9, the secondary filter body 802 is first snapped into the interior of the secondary filter snap-fit ​​seat 801, thereby achieving secondary filtration of impurities and preventing impurities from entering the lower drain pipe 6 from the high-level steel structure base 8 and the split filter box 9.

[0084] When installing the steel structure base 8 and the split filter box 9, the steel structure base 8 and the split filter box 9 can be directly snapped together. When installing the inspection cover body 13, the inspection cover body 13 is locked with the inspection cover slot 803 of the steel structure base 8, thereby limiting the position of the split filter box 9.

[0085] When installing the primary large-pore filter 10, first pull the second unlocking handle 1104, causing the second unlocking handle 1104 to drive the second sliding column 1101 and the second locking rod 1102 to move. This causes the second sliding column 1101 to compress the second spring 1103, at which point the primary large-pore filter 10 is snapped into the inside of the locking rail 901. Then release the second unlocking handle 1104, and the second spring 1103 stretches and pushes the second sliding column 1101 and the second locking rod 1102 to move, causing the second locking rod 1102 to insert into the inside of the second locking hole 1001, thus achieving the installation and fixation of the primary large-pore filter 10. When cleaning, maintenance, or replacement of the primary large-pore filter 10 is required and it needs to be disassembled, the installation and fixation process is reversed.

[0086] When locking the inspection cover body 13 to the inspection cover slot 803 of the steel structure base 8, first pull the first unlocking handle 1304 so that the first unlocking handle 1304 drives the first sliding column 1301 and the first locking rod 1302 to move and squeeze the first spring 1303. At this time, the inspection cover body 13 is locked to the inspection cover slot 803. Then release the first unlocking handle 1304. The first spring 1303 stretches and pushes the first sliding column 1301 and the first locking rod 1302 to move, so that the first locking rod 1302 is inserted into the first locking hole 8031, thereby realizing the installation and locking of the inspection cover body 13. When disassembling the inspection cover body 13, the installation and fixing process is reversed.

[0087] When the internal water channels of the drainage pipe 6 and the water channel pit 7 are unobstructed, the water level monitoring mechanism is in normal operation. The buoyancy of the water flow inside the split filter box 9 causes the buoyancy block 1205 to float. Due to the smooth drainage, the water level inside the split filter box 9 is low, and the buoyancy block 1205 does not contact the pressure sensor 1204. Therefore, the communicator 1203 is in normal standby mode and does not send a signal.

[0088] When a blockage occurs in a certain section of the internal waterway of the drain pipe 6 and the waterway pit 7, and drainage is not smooth, the water level inside the split filter box 9 rises, thereby causing the buoyancy block 1205 to slide upward. When the buoyancy block 1205 contacts the pressure sensor 1204, the pressure sensor 1204 displays a value and triggers the communicator 1203 to work and send a signal to remind of the blockage location.

[0089] Each set of communicators 1203 and waterway foundation pit 7 is numbered and assigned a corresponding location, so that staff can be quickly alerted to the locations that need to be inspected and cleared.

[0090] The higher the water level inside the split-type filter box 9, the greater the distance that the buoyancy block 1205 pushes upward against the pressure sensor 1204, the greater the squeezing force of the third spring 1202, and the greater the force detected by the pressure sensor 1204. Therefore, the water level and blockage status inside the split-type filter box 9 can be indirectly determined by the detection force of the pressure sensor 1204.

[0091] In summary, this cast-in-place concrete pavement structure utilizes a permeable pavement structure formed by a large-diameter permeable crushed stone layer 2, a small-diameter permeable crushed stone layer 3, a permeable leveling layer 4, and a decorative permeable surface layer 5. Water infiltrates directly without forming runoff, preventing road surface flooding. Multiple sets of drainage pipes 6 and a water channel pit 7 further enhance the pavement's permeability and drainage capacity. Inside the water channel pit 7, a steel structure base 8, a split-type filter box 9, and a primary large-aperture filter screen 10 are installed. The primary large-aperture filter screen 10 traps impurities at various drainage sections, preventing blockages in the drainage pipes 6. The split-type filter box 9, located inside the steel structure base 8, is easily disassembled, ensuring convenient cleaning and maintenance of both the filter box 9 and the primary large-aperture filter screen 10. Combined with a water level monitoring system, the system can quickly locate blocked or flooded sections within the reinforced drainage channel formed by the drainage pipes 6 and the water channel pit 7, enabling rapid clearing of blockages, preventing road surface flooding, and ensuring road safety.
